MOLD

. Specification of Letters Patent. Patented March 16, 1909;

Application filed June 5, 1908. Serial No. 436,923.

To all whom it may concern:

Be it known that I, W ILLIAM E. FRosT, a citlzen of the United States, residing at Highland Mills, in the county of Orange and State of New York, have invented certain new and useful Improvements in Molds, of which the following is a specification, refer ones being had to the accompanying drawings.

My invention relates to improvements in molds for making blocks of cement, concrete or other plastic material and particularly blocks used in constructing utters.

My invention further re ates to an improved concrete gutter block.

The object of the invention is to provide a simple and practical molding device by means of which my improved gutter blocks may be uickly made.

W'ith t e above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of arts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my improved concrete gutter block; Fig. 2 is a similar View of my im roved mold for making the blocks; and igs. 3 and 4 are longitudinal and transverse sectional views through the mold and one of the blocks therein.

My improved gutter block may be molded of cement, concrete or any other suitable plastic material and comprises a substantially rectan ular body 1 having in its top a longitudina channel 2 which extends from end to end of the block and forms a portion of the gutter, in use the blocks being placed end to end so that their channels form acontinuous gutter. The block is reinforced by two straight longitudinally extending wires 3 and by two or more lon itudinally curved and transversely dispose wires 4 embedded in the block, as clearly illustrated in the drawings.

My improved mold comprises arectangular base 5 u on the four edges of which are hinged si es 6 and ends 7. The sides 6 are connected to the base by strap hinges 8 so that they swing downwardly and outwardly and when elevated they lie within the plane of the side edges of the base. The ends 7 of the mold are connected by strap hinges 9 to the bottom of the base 5 so that they also swing downwardly and outwardly and when in their vertical position they abut the ends of the sides 6 and the base 5, as illustratedi Pivoted hooks 10 upon the sides 6 are adapted .to engage keeper eyes 11 on the ends 7 to I hold the mold in its closed position.

The mold corresponds in width to the width of the gutter block and it is referably made twice as long as the blOCYi so that two blocks ma be simultaneously formed in it. These b ocks are separated by a partition 12 which is removably mounted in opposing vertical grooves 13 formed in the inner faces of the sldes 6. In the bottom of said partition. or dividing plate 12 is a semi-circular recess 14 adapted to receive a semi-circular rib 15 arranged upon the center of the top of the base 5 so as to form a core which molds the groove or channel 2 in the block. The core 15 extends longitudinally of the base from end to end so that when the sides and ends of the mold are elevated and the partition 12 is in osition between the sides the space within t e mold will be divided into two com artments each the exact shape of one of the blocks. By hinging the sides and ends of the mold and providlng one or more of the partitions 2 two or more blocks may be simultaneously molded and they may be readily removed from the mold after they have set by unfastening the sides and ends and swinging them downwardly to their open position.

In using the mold it is closed and the partition is placed within it and its two sections are then artially filled with plastic material. The rein orcing wires may be then placed in even with the upper edges of its sides, ends and artition to complete the blocks. After the blocks have become set they may be readily removed as above explained. By embedding the reinforcing wires in the blocks they will be rendered exceedingly strong and durable.

Having thus described my invention what I claim is:

Theherein described mold for making gutter tiles comprising a rectangular base, a core secured upon the, top of the same and end, outwardly swinging sides formed in their opposin faces with vertical grooves, hinges for saiil sides, each hinge having one leaf secured to one of the side edges of the base and its other leaf secured to the outer face of one of said sides whereby the lower edges of the latter will rest upon the top of the base when in their upright position, outposition in. the material and the mold filled extending longitudinally thereon from end to wardly swinging ends, hinges for said ends slidably engaged with the opposing grooves each of said hinges having one leaf secure in said sides and formed in 1ts bottom with to the bottom face of the base and its other a recess shaped to receive said core. leaf of angular shape and secured to the bot- In testimony whereof I'hereunto aflix my 5 13011111 egge zltndl outer fafiieof one 05 the iendsf signature in' t 1e presence of two witnesses. 15
